Cold hardy ... i find it very difficult to believe that where i am is in zone 6a. We planted grapes a few years ago that were hardy to zone 5 and they couldn't take it, plus we lost our best peach tree due to winter cold ... and we almost never can plant our garden before June 1 without having to worry about frost. i get plants rated for zone 4 and they do well.

BEST ANSWER:Yes you should plant as soon as possible. if your conditions are too cold you can keep them in a cool place and keep them damp. not wet but damp with some wet newspaper or something similar. However I recommend not storing them before planting for more then a few weeks.

BEST ANSWER:This grape goes dormant just like most other grapes. The leaves do seem a little more green but not abnormally so throughout the winter months. I mulch the base's well in the winter with straw and pick up the leftover straw and put on the garden in the spring. Very good compost.

BEST ANSWER:Yes, but if you think about it, the vine will not be growing straight up that tall. On a fence, trellis or arbor, you're redirecting that "height" to the side ??? or better yet, pruning it to maintain your grape vine in your growing space, keeping it manageable and encouraging fruit production.

Customer Reviews

Fabulous Flavour! Fantastic for Jelly! Super Hardy! Great growth characteristics! I have 5 plants which I put out in fall of 2008. All are doing extremely well. At the same time I planted 6 other varieties. Three of them have not survived. The other 3 are not as well behaved in growth characteristics... having many suckers at base which need pruning all season. The St Theresa does not sucker at the base after initial training. The Fruit cropping is VERY HEAVY.... it gives a great harvest! The seedless nature makes it a wonderful table grape. It raisons well in my solar food dryer. I have not complaints.... nor aspirations for anything better.

I have 6 varieties of grapes that I planted in 2015. The St t's are growing better than most of the others. No fruit as expected yet. The somerset's have born fruit in each of their 2 yrs. The st t's plants are looking strong and healthy. My climate is a 4.5 and very arid. I have irrigation rights that is required to grow anything up here in N Wy.

Got my vines and planted them. They made it trough winter and a very hot summer right now. The vines look good and have grown enough to be trellised. I hope to have my first crop in the spring. They were slow to start and require a lot of water initially, but have thrived with our summer afternoon rains here in Florida. So far so good. Hard to get a bunch grape to grow here.

It is a little premature for me to be writing a review of this grape but since I was asked, I'll tell you what I know. My plant is too young to be bearing yet. What I was looking for is a vine that will tolerate some shade. Saint Theresa seems to do that quite well. It has grown and spread across the trellis quite well. I expect there will be some grapes next summer.My main problem this year has been keeping the Japanese Beetles from destroying it. They REALLY like it.I tried Muscadines in this location a couple of times and failed completely, so the Saint Theresa has been a pleasant surprise, so far.

I had very good growth the first year. They came back in spring just fine after a normal winter in zone 4. Growth rate was good and not too aggressive. No grapes yet. But I can see this is going to be a good grape for northern gardens. I am going to buy more.

I wasn't expecting much after a dismal first couple of months after planting. Come this second season, absolutely fantastic. The vine has tripled in length, and clusters are popping up everywhere. I'm very satisfiedwith with this purchase.
